The Toronto Zoo is celebrating a towering new arrival this week after welcoming the birth of a healthy Masai giraffe calf.The female calf was born at 1:26 a.m. on Feb. 22 and was standing on her own within roughly 30 minutes, according to zoo officials. A preliminary health check on Monday confirmed she is doing well, measuring an impressive 6 feet 4 inches (1.95 metres) tall.“This endangered Masai giraffe calf is an incredible addition to your Toronto Zoo,” said Dolf DeJong, the zoo’s CEO. “We announced Mstari’s pregnancy on Mother’s Day last year, and after a 15‑month pregnancy, we are thrilled to have a healthy calf in our care, raising the profile of endangered Masai giraffes and inspiring our community to learn more and stand with us as Guardians of Wild.”Related:Toronto Zoo says postmortem report shows Kiko the giraffe died of cardiac arrestThe newborn is the offspring of Mstari, a well‑known member of the zoo’s giraffe herd.
